Description

一种带有灰尘吹落结构的盐芯夹放装置 技术领域
本发明涉及铸造设备技术领域，具体为一种带有灰尘吹落结构的盐芯夹放装置。
背景技术
活塞是发动机的基础零部件之一，是发动机的心脏。目前汽车活塞正在朝着高强度、高耐磨度、高精密度、低膨胀、轻量化、结构组合化的方向发展。在生产过程中，一方面，活塞在铸造时需要完成的工艺越来越多，包括镶钢片、镶耐磨镶圈、放置盐芯等；另一方面活塞的轻量化需求使得活塞的结构越来越复杂，对生产工序的要求变得越来越严格。
在对活塞毛坯进行浇铸时，需要安装盐芯到模具支撑上。现有技术中已经出现很多自动化的设备用于安装盐芯。例如公告号为CN209272401U的中国专利公开了一种快装盐芯工作台，包括浇铸台和盐芯预热装置，浇铸台上安装有浇铸模具，浇铸台上开设有安装槽，安装槽侧壁开设有滑槽，浇铸模具滑动安装于滑槽内，浇铸模具包括模盖、开合外模和内模，内模连接有上料机构，浇铸台一侧安装有盐芯预热装置，它可自动安装盐芯，自动化能力较强，有利于提高生产效率，减低人工负担，安全性较好。
公告号为CN208033575U的中国专利公开了一种盐芯加热输送机，包括驱动机构、储盐芯桶、输送网带、加热炉和底座，所述驱动机构、储盐芯桶、输送网带、加热炉安装于底座上，所述输送网带上等距安装有拨盐芯杆。该实用新型结构设计合理，本装置一方面实现了盐芯自动供给和加热，与机器人配合使用可实现机器人取代人工放置盐芯，实现活塞浇铸过程盐芯放置自动化，另一 方面本装置适用范围广，可用于各种盘状物体的输送，具有较高的实用性。
在盐芯加热和安装之前需要擦拭盐芯，将盐芯上的灰尘擦掉，但是，在上述两个发明中并没有设置相应的除尘装置，仍然需要人工擦拭。
发明内容
针对现有技术存在的不足，本发明提供一种带有灰尘吹落结构的盐芯夹放装置。
一种带有灰尘吹落结构的盐芯夹放装置，包括机械臂、与机械臂固定连接的工作架以及若干等距离间隔分布于工作架底端的气缸夹爪，所述气缸夹爪包括气缸部分和位于气缸部分底端的夹爪部分，所述气缸部分的底端中心位置固定有连接杆，所述连接杆的底端固定有位于夹爪部分内的压盘，所述压盘与夹爪部分的底部之间保留有用于夹取盐芯的间隙，所述工作架的内部设置有与外部的气泵通过管道连接的气路管，所述气路管上连接有若干向工作架外延伸的吹气管，若干所述吹气管分别与各个气缸夹爪的位置对应，且所述吹气管的出气端朝向夹爪部分。
通过采用上述技术方案，先通过机械臂移动工作架从而移动气缸夹爪至盐芯位置，通过气缸夹爪夹取盐芯，再通过机械臂将盐芯移动至指定安装位置。在将盐芯移动至指定安装位置的过程中同时通过外部的气泵给气路管供气，气体经过气路管从吹气管的出气端吹出，从而将盐芯上的灰尘吹落。本发明能够自动对盐芯进行除尘处理，无需人工进行擦拭，极大地提高了工作效率。
本发明的进一步设置：若干所述吹气管上均设置有控制阀。
通过采用上述技术方案，实现各根吹气管的独立吹气，避免某个气缸夹爪没有抓取盐芯时，与该气缸夹爪对应的吹气管仍在吹气。
本发明的进一步设置：所述工作架的底端面背离吹气管的一侧还固定有防 尘罩，所述防尘罩上靠近夹爪部分的一侧开设有与夹爪部分位置对应的进气口，所述工作架的外侧壁上还固定有吸尘器，所述吸尘器与进气口之间通过管道连接。
通过采用上述技术方案，在吹气管吹气的同时，启动吸尘器，通过管道将灰尘吸入吸尘器中，防止灰尘进入空气中，对工作人员造成危害。
本发明的进一步设置：所述工作架的底端开设有若干与气缸夹爪位置对应的转孔，所述气缸部分的顶端固定连接有转轴，所述转轴的顶端通过转孔穿入工作架内，且所述转轴与转孔的孔壁通过轴承转动连接，所述工作架内设置有电机，所述电机的输出轴与转轴通过联轴器固定连接。
通过采用上述技术方案，在将盐芯移动至指定安装位置的过程中同时也启动电机，电机的输出轴旋转带动与其固定连接的转轴旋转，转轴的旋转带动气缸夹爪旋转，气缸夹爪旋转带动盐芯旋转，从而使盐芯上的各个角度都可以被吹气管吹到，保证吹气管可以将盐芯上的灰尘完全吹除。
本发明的进一步设置：所述电机还设置有减速机，所述减速机的输出端与转轴固定连接。
通过采用上述技术方案，通过减速机的设置，使转轴匀速缓慢地旋转，从而使气缸夹爪匀速缓慢的旋转。
与现有技术相比，本发明的有益效果是：
一种带有灰尘吹落结构的盐芯夹放装置，先通过机械臂移动工作架从而移动气缸夹爪至盐芯位置，通过气缸夹爪夹取盐芯，再通过机械臂将盐芯移动至指定安装位置。在将盐芯移动至指定安装位置的过程中同时通过外部的气泵给气路管供气，气体经过气路管从吹气管的出气端吹出，从而将盐芯上的灰尘吹落。本发明能够自动对盐芯进行除尘处理，无需人工进行擦拭，极大地提高了 工作效率。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
一种带有灰尘吹落结构的盐芯夹放装置，如图1和图2所示，包括机械臂1、与机械臂1固定连接的工作架2以及若干等距离间隔分布于工作架2底端的气缸夹爪3，工作架2的底端开设有若干与气缸夹爪3位置对应的转孔，气缸夹爪3包括气缸部分4和位于气缸部分4底端的夹爪部分5，气缸部分4的顶端固定连接有转轴14，转轴14的顶端通过转孔穿入工作架2内，且转轴14与转孔的孔壁通过轴承转动连接，工作架2内设置有电机15，电机15连接有减速机16，减速机16与电机15的连接为成熟的现有技术，在此不做具体描述，减速机16的输出端与转轴14通过联轴器固定连接，气缸部分4的底端中心位置固定有连接杆6，连接杆6的底端固定有位于夹爪部分5内的压盘7，压盘7与夹爪部分5的底部之间保留有用于夹取盐芯的间隙，工作架2的内部设置有与外部的气泵通过管道连接的气路管8，气路管8上连接有若干向工作架2外延伸的吹气管9， 若干吹气管9分别与各个气缸夹爪3的位置对应，且吹气管9的出气端朝向夹爪部分5，若干吹气管9上均设置有控制阀10，控制阀10为成熟的现有技术，在此不做具体描述。
工作架2的底端面背离吹气管9的一侧还固定有防尘罩11，防尘罩11上靠近夹爪部分5的一侧开设有与夹爪部分5位置对应的进气口12，工作架2的外侧壁上还固定有吸尘器13，吸尘器13与进气口12之间通过管道连接。
工作原理：先通过机械臂1移动工作架2，从而移动气缸夹爪3至盐芯位置，通过气缸夹爪3夹取盐芯，再通过机械臂1将盐芯移动至指定安装位置。在将盐芯移动至指定安装位置的过程中同时，打开控制阀10，外部的气泵给气路管8供气，气体经过气路管8从吹气管9的出气端吹出，同时启动吸尘器13和电机15。吸尘器13通过管道将灰尘吸入吸尘器13中，防止灰尘进入空气中，对工作人员造成危害。电机15的输出轴通过减速机16匀速缓慢地旋转并带动与其固定连接的转轴14旋转，转轴14的旋转带动气缸夹爪3旋转，气缸夹爪3旋转带动盐芯旋转，从而使盐芯上的各个角度都可以被吹气管9吹到，保证吹气管9可以将盐芯上的灰尘完全吹除。当盐芯移动至指定安装位置时，松开气缸夹爪3，并通过机械臂1移动工作架2下压，从而带动压盘7下压在盐芯上，最终完成盐芯的安装。值得注意的是，在机械臂1移动的过程中，无论是夹取盐芯还是安装盐芯，始终只保持工作架2上安装有气缸夹爪3与压盘7的一侧对应到夹取处和安装处，即防尘罩11的设置，不会影响到气缸夹爪3的夹放以及压盘7的下压。
本发明能够自动对盐芯进行除尘处理，无需人工进行擦拭，极大地提高了工作效率。
